In Datameer X you can create a workbook to get to new insights with your data. Inside the workbook, you can add additional data sources, change the column and sheet names, collapse columns, apply formulas, view workbook details, and more.
You can also copy workbooks, import worksheets from other workbooks, duplicate workbooks and worksheets, and exchange datasources.
You don't have to save anything at any time. Each action, which is done in a workbook, is automatically saved.
